Privacy Policy

This page explains what StatCalcs does and does not collect. In short: the calculators run entirely in your browser, and we do not ask you to create an account or hand over personal data to use them.

What stays on your device

The numbers you type into a calculator are processed in your browser and are not sent to us. If you choose to save inputs or preferences (for example, dark mode), those are stored in your browser using local storage, on your device only. Clearing your browser data removes them.

Analytics

We use Cloudflare Web Analytics, a privacy-friendly, cookieless tool, to understand which calculators are used, in aggregate. It sets no cookies and does not identify individual visitors, so no cookie banner is required for it.

Advertising

StatCalcs plans to display ads through Google AdSense to keep the tools free. Until AdSense is live, no advertising cookies are set. When ads go live, this section will describe the cookies AdSense uses and how to opt out via Google's ad settings.
